How to Choose Which Puppy to Keep from Your Litter

The best puppy to keep depends on its intended role. Compare littermates consistently, put health ahead of cosmetic preferences, and treat early behavior as an impression, not an adult temperament guarantee.

Choose the puppy whose health, suitable conformation, and observed behavior best fit the role you intend it to fill—not simply the one with your favorite color, markings, or sex. The right priorities differ for a breeding prospect, show dog, working dog, or companion, so start by defining your goal and assess each puppy against the same criteria.

1. Decide what you are keeping the puppy for

There is no universal best puppy in a litter. The qualities that matter most depend on your purpose, the breed, and the work or life you expect the dog to have. Dogs Victoria’s 2024 breeder guidance frames selection around the breeder’s criteria and aspirations; Cornell’s guidance likewise emphasizes choosing in light of the intended fit.

Breeding prospect

For a potential breeding dog, consider whether the puppy may contribute to your long-term breeding goals while meeting relevant breed standards and health priorities. Do not treat a puppy’s appearance or early promise as proof that it will be an appropriate breeding animal; reassess as it matures and use breed-specific health information and qualified veterinary advice.

Show prospect

If you hope to show the dog, compare puppies against the applicable breed standard and your realistic goals. A young puppy’s conformation is still developing, so an early choice cannot guarantee how it will look or perform as an adult.

Working prospect

For a working role, identify the traits and abilities the task actually requires. Breed and task priorities differ, and no single temperament or activity level is right for every kind of work. Observe behavior in ordinary situations rather than relying on one dramatic moment.

Companion

If you are keeping a puppy primarily as a companion, prioritize health and a good fit with your household and the care you can provide. Breeding or show conformation alone does not establish that a puppy is the best companion for you.

2. Put health and suitable conformation ahead of cosmetic preferences

Dogs Victoria advises breeders to aim for the healthiest, best-conformed puppy, regardless of sex, color, or markings. Use that as a useful order of priorities: first look for health and soundness, then consider whether the puppy’s physical qualities suit its intended role. Attractive markings or a preferred sex should not outweigh a meaningful health concern.

Review the information available

  • Ask what health screening has been done for the parents and what results are available. The relevant tests vary by breed, so do not assume one generic checklist applies to every litter.
  • Review the puppies’ veterinary records and ask about any examination, treatment, or concern that applies to an individual puppy.
  • Consider the puppies in their rearing environment, alongside the mother and the breeder’s health and care practices. These provide context that a quick look at one puppy cannot.

Resources from the Royal Kennel Club on researching puppy parents’ health and the RSPCA on finding a good breeder can help frame questions about parental health and breeding practices. They do not replace a veterinarian’s assessment of an individual puppy.

Arrange an appropriate veterinary assessment

General selection advice cannot diagnose a puppy’s health. If you have a concern, or need an individual assessment before deciding, ask a veterinarian to examine the puppy and explain what the findings mean for its likely care and intended role. A veterinarian can assess health; they cannot guarantee a puppy’s adult development.

3. Observe behavior over time, not in a one-off test

Watch how each puppy behaves during ordinary interactions and across more than one occasion. Note activity, responses to people and surroundings, and how the puppy settles after excitement. Interpret those observations in light of the role you have chosen and the puppy’s age and environment.

Do not treat a brief test of a very young puppy as a reliable forecast of its adult temperament. VCA Animal Hospitals cautions that accurate temperament testing is not possible at a very young age. Early behavior can offer a general impression, but it cannot guarantee how the dog will behave later.

Compare the candidates consistently

When several puppies remain under consideration, use the same questions for each rather than relying on an overall impression or an invented numerical score:

  • Which puppy best fits the role I have defined?
  • What relevant health information is available for this puppy and its parents?
  • What physical soundness and conformation can I observe, and how relevant are they to that role?
  • What behavior have I seen across ordinary interactions, rather than in one brief test?
  • Can I provide the environment, management, and care this puppy will need?

Breed-specific health tests, conformation priorities, and working requirements cannot be set responsibly without knowing the breed and intended role. Use the relevant breed guidance and professional advice rather than applying a generic ranking to every litter.
